Is the RainControl only for use with rainwater?

Simply, no. The RainControl can be used with other fluids. As long as the pressure sensor being used is tolerant of the fluid (viscosity, temperature, pH etc.) the RainControl can be used.

Do I need to build a panel around the RainControl?

Not at all. The RainControl functions as a level controller on its own. However, you can use the output from the RainControl to operate other components of a larger controller.

I’m trying to maintain a minimum tank level, from either mains water or a holding tank. Is the RainControl suitable for this?

Absolutely! The RainControl is totally suitable for maintaining a minimum tank level from either mains water or a holding tank. It can activate/deactivate a pump, solenoid, or simple mechanical valve using its onboard relay. The only thing you need to do is define the activation range, which includes the levels for activation and deactivation.

I need to set a high-level alarm on a holding or process tank. Should I consider using the RainControl, or do I need to create something from scratch?

This is a slightly trickier scenario. Yes, the RainControl can be used as a high-level system by triggering a beacon or sounder, depending on the location and ambient noise. However, if you need to activate a local beacon, or a remote beacon, and open a spillway or overflow solenoid, this would require a more complex controller. You would need to use the output from the RainControl to drive either a secondary controller or relays for this purpose.

I want to keep a tank at a minimum level, as in I want to hold water in a tank and release it over time, along the lines of a retention tank. Would the RainControl work in this situation?

I particularly liked this question. The answer is yes! With a little planning, a throttled outlet with a motorised valve can be activated by the RainControl. It really is only a matter of calculating the required flow rate and minimum tank level. Of course, if we wanted to get a little clever, the designer could add other functions like a high-level alarm or discharge notification by using the RainControl output to drive multiple relays. A setup like this can be as simple or complicated as the designer (or user) wants, and all centralised around a simple little box.

I have another potential use for the RainControl Tank Level Controller who can I contact for more information?

As always, with any of the Mac3 products, we are always happy to discuss them in greater detail and how they can be deployed in your designs or installations. Contact Jim, our Mac3 Technical lead. Jim and Tom have over 25 years of experience in Water Control Systems.
